Answer:
mp=sp+25%ofsp=1.25sp
mp=1.25sp
sp=1/1.25×mp=0.8mp
cp=mp-30%ofmp=0.7mp
discount=mp-sp=mp-0.8mp=0.2mp
- discount %=discount/mp×100%=0.2mp/mp×100%=20%
- profit=sp-cp=0.8mp-0.7mp=0.1mp
- profit%=profit/cp×100%=0.1mp/0.7mp×100%=0.1×100/0.7%=10/0.7%=14.28%
Answer: 14 meters
Step-by-step explanation:
Use the pythagorean theorem to solve.
12 ² + 8 ²= c ²
208= c ²
√ 208 = √ c ²
14.42= c

Hello!
The equation for a circle is

r is the radius
To find the radius we take the square root of the number in the radius spot
sqrt169 = 13
The answer is 13
Hope this helps!
Answer:
see explanation
Step-by-step explanation:
The area of the shaded portion is the area of the outer circle subtract the area of the inner circle
area of larger circle = πr² ← r is the radius = 11
area = π × 11² = 121π
area of smaller circle = πr² ← r = 9
area = π × 9² = 81π
-----------------------------------------
shaded area = 121π - 81π = 40π m² ≈ 126 m²
Answer:
1.) 7. (7 x 7 = 9)
2.) IDK, sorry
3.) 8/27
Apply the product rule to 2/3
2^3/ 3^3
Raise 2 to the power of 3.
8/27
4.) 9
1. Exponentiation: 3 ^ 4 = 81
2. Exponentiation: 3 ^ (-2) = 0.111111111111 = 1/9
3. Multiple: the result of step No. 1 * the result of step No. 3 = 81*1/9 = 81 · 1/1 · 9 = 81/9 = 9 · 9/1 · 9 = 9
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(81, 9) = 9. Cancelling by a common factor of 9 gives 9/1.
In words - eighty-one multiplied by one ninth = nine.
4. Exponentiation: 3 ^ 0 = 1
5.Multiple: the result of step No. 4 * the result of step No. 5 = 9 * 1 = 9
5.) 1/125
5 ^ (-3) = 0.008 = 1/125
6.) IDK, sorry
